To a-ZZ whom it may concerm- 'y Be it known that we, Sims B. Tamron and WILLIAM H, KELLY, citizens oit the United States, residing, respectively, at Seattle, in the county of King and State of Washington, and Los Angeles, in the county of Los ngeles and State ot Calitornia,have invented a new and useful Oil-Burner, of which the following is a speciicat-ion.`

The main object of the present inventidp is to provide an oil burner which will impartto the issuing jeta rotary or swirling motion.

A further object of the invention is to provide an ,oil burnerV in which the-oil will be mixed withthe atomizing fluid or medium by 'means of a rotary or swirling move- ,lnent (lther'objects of the invention will appear Ahereinatter.

5 The accompanying drawings illustrate the re 1 is a longitudinal vertical section 2 is a horizontal section Fig. 1. Fig. B is a front. elevation ot the burner tube. Fig. 4- is a partial sectional elevation ot a different if'orrn of the invention. lig. 5 is a "front, end elevation of the form shownin Fig. 4. Fig. (i is a fragmentary horizontal section on line act-ar in Fig. 5.

Referring to Figs. 1 to 3, the burner comprises a body portion or fitting 1, a mixing tube 2 screwing in or otherwise secured to said body portion.` and a central tube 3 extends longitudinally through the body portion 1 and through the tube 2 and is adapted to supply steam or expansive fluid to the center ot the pulverized oil and steam mixed therewith. The tube 2 is provided with an outlet cap or nozzle 4 having a discharge orifice 5 surrounding the outlet end of the tube 3, said outlet end of the tube 3 being reduced` or tapered, as shown. at 3, so that it is somewhat. smaller than thesize of opening Tube 2 is screw threaded7 as at 6, to screw within the member 1 so as to adjust the area of the outlet at the opening 5, a handle 'i' being provided to facilitate' such adjustment, and a loclr nut 8 being provide to lock the tube 3 in any position to which it may be adjusted. Tube 3 is provided at its rear end with any suitable connecting means whereby steam, oreizftmple, super- Figo on the line m2--m2 heated steam, or air under pressure or undery atmospheric pressure is admitted to the center of thecombustibles.

The oilis supplied by means of a pipe 10 screwing into a recess or chamber 11 in the body 1, the bottom ot said recess communi eating through a horizontal slot- 12 with the space between tubes 2 and At the .rear of the recess 11 another recess 13 is provided communicating with a steam supply pipe 14, said recess 13 opening into 'recess 11 through a channel or'horizontal slot 15 in line with the sl t 12 aforesaid, so that the pressure of steam issuing through slot 15 will drive the oil from recess 11 through the slot 12 and into the mixing chamber between the tubes 2 and3. i

The mixing chamber between the tubes 2 and3 isprovided with a spiral detlector or baii'le pla-te 17 formed, for example, of a band or strip of metal bent in helical shape so that a spiral passage is provided for the oil and the elastic fluid or steam,A and the oil and steam traversing this passage from the rear tothe delivery end of the tube 2 is a itated, broken up and thoroughly,

mixe l The o ration is as follows: Oil issup plied at pipe 10 and is forced from recessll by the ress'ure ot' the steam admitted by the pipe, 14,1 as above described, and in its passage between the tubes 2 and ii is spirally deflected by the detiector 17 and thereby :itemized-and mixed with the steam, the tube 17 serving as a baffling device tor insuring complet-e mixture. 5 the mixture of oil and steam is ejected forcibly and the air or steam issuing through the tube 3 and outlet 3 mingles centrally therewith, the issuing jet of steam retaining its swirling or rotary movement induced by the action of the deiiect-or 17 aforesaid mingles and combines the pulverized combustibles and the additional supply of air or steam, y

ln case a fiat jet or Flame is desired the construction shown in Figs. 4, 5 and. Ginay be adopted, the burner tube 20, head 21 .and detlector 22 being constructed substantially, as above described,` the nozzle cap 24 being provided with a horizontally elongated slot i 25 and the tube 23 being provided with a horizontally elongated slot `23 in line with the slot 25. As shown the elastic fluid pipe 2 serving'as a mixing chamber and deiie'ctor y On reaching, the outlet' is tapered lfrom' t he front end rearwardly to fit into the tapered orifice in the burner tip and by screwing the expansive fluid pipe 'forward the area of the orifice in the tip may be regulated as desired. The flame can be regulated by this means Without the aid of valves in the steam or oil lines, `and if desired by closing the orifice in the burner tip the pressure of the steam may be utilized to force the oil back through the oil pipe to clean the same. The outlet tip et is detachably secu-red to ,the end of the tube 2 and is readily remoied therefrom, thereby facilitating the renewal of the orifice in case the same should become Worn out, Wi thout the necessityor expense of providing an entirely completeV new body. Such tip may be madeof special meta-l and may be hardened to resist wear, and by making the same detachable from the -tube 2, We avoid the necessity of providing an entire new tube and the attendant time and labor of Ireplacement when the orifice becomes Worn.

at We claim isz `1. An oil burner comprising a mixing tube having a contracted outlet at one end,

a member closing-*the other end of said tube and provided with steam inlet means and 4oil inlet'means communicating with the interior of sid tube, andan inner tube for supply ofi elastic fluid extending through said member and longitudinally Within the mixing tube and through the outlet thereof and .having an outlet beyond the outlet of y the I the' mixing tube to deliver elastic fluid .he youd the outlet of the steam and oil from the mixing tube, said inner tube being tapered at its delivery" end and being longitudinally adjustable within the mixing tube, 2. An oil burner comprising a body niember having an oil receiving; recess, an oil pipe communicating therewith, said recess having a delivery slot, said body member having a steam receiving recess with a delivery slot in line with the aforesaid oil le livery slot, steam supply means eommuuieat ing with said steam recess, u tubular member secured to the said burly member and communicating with the oil delivery slot to receive oil therefrom, and provided :it ils farther end with an outlet, an elastic fluid supply pipe extending longitudinally through the body member and the tubular member and adjustable longitudinally therein and provided at its end with a discharge orifice 1n line with the aforesaid outlet of tubular member, and a spiral delico-tor extending Within the tubular member und in the space between the same and the said elastic fluid supply pipe.
